How do we achieve a gas tight joint when manufacturing cylinder heads?

Fabricate the entire assembly from forged aluminum

A heat resistent silicone-based sealant

Cast iron

Cast magnesium

Nickel or chrome alloys

Forged aluminum

5.

1 point

What is the mounting flange?

The top of the cylinder where the head screws on

The component that prevents oil from draining into the combustion chamber on radial engines

Used to attach the cylinder to the crankcase

The location where the exhaust pipe is bolted on

6.

1 point

What is a choke bore cylinder?

A cylinder machined with a slight taper at the top of the bore

A cylinder machined with a slight taper at the bottom of the bore

A cylinder with an integral choke to aid in starting

A cylinder with a uniform bore dimension from top to bottom

7.

1 point

How do we minimize cylinder barrel wear and increase its service life?

Low compression pistons

Regular inspections

Hardening

Use only aviation grade engine oil

8.

1 point

When a cylinder barrel is machined, heated, and exposed to ammonia gas how is it said to have been treated?

Nitrided

Honed

Chromed

Forged

9.

1 point

How do we identify cylinder barrels that have been nitrided?

A white stripe

No special identification is required

A blue stripe

An orange stripe

10.

1 point

What is a disadvantage of nitrided cylinders?

The hardened surface contributes to greater piston wear

They are more susceptible to corrosion if unused for long periods of time

The heads are susceptible to dissimilar metal (galvanic) corrosion

The interior or the barrel will not hold oil for extended periods of time

11.

1 point

Another term used to describe the process of chrome plating is...

Friction plating

Spalling

Surface machining

Electroplating

12.

1 point

Are chrome cylinder bores more of less likely to corrode as compared to steel or nitrided cylinders?

More

They are neither more nor less likely, it is just a different process

Less

13.

1 point

How do we identify cylinders that have been chrome plated?

An orange stripe or band

A white stripe or band

If no identifying mark is present, we can safely assume it has been chromed

A blue stripe or band

14.

1 point

What is a problem associated with chromed cylinders?

The smooth surface does not retain oil to lubricate the piston rings

The surface cannot be re-chromed once it wears beyond its serviceable limits

The surface is so hard it causes premature wear on the pistons

There are no known difficulties with this process

15.

1 point

What is a characteristic of the paint that is applied to the exterior of cylinders?

Protects the cylinder from corrosion

Hardens the exterior for lasting durability

Changes color indicating a possible overheat condition

It identifies the cylinder as being either a Lycoming or Teledyne Continental product
